Q: What does "SLF" stand for?

ASmoother, Lighter, and Faster


Q: Will using SLF Motion products make me faster on my bike?

A: In short, YES!  SLF Motion cycling products are designed to reduce drivetrain friction therefore allowing the user to go faster with less effort.  Along with decreased friction, the user is also gaining unmatched durability thanks to the use of coated bearings and CNC machined pulley wheels.


Q: Do you offer a warranty on your products?

A: All Pulley Wheels, Speed Systems, AERO Systems, and Adventure Systems are covered by our Lifetime Warranty for the original purchaser (non-transferable).  This warranty does not cover the surface finish of pulley wheels, such as anodize coloring and/or Oil Slick coating, as this would be considered "normal use wear items".  Please note - the Oil Slick effect is created via a "coating" process...therefore is not a permanent application...over time, this coating will likely begin to chip away during use.


Q: I'm afraid to install an Adventure System onto my MTB/Gravel due to the increased size of the System.  Will the bigger System be more prone to getting damaged?

A: Seen in the photo below, the height/size of each cage is nearly identical therefore the Adventure System is no more-so in danger than a stock cage. Pictured below is a stock SRAM Eagle cage next to our Adventure Eagle System...

Q: Will I need a new chain when installing an Oversize System?

A: This is dependent on a few things.  If you are upgrading to an Oversize System from a competitors' Oversize System, then NO you will not need a new chain.  If you are installing a new Speed or AERO System onto a stock rear derailleur (meaning currently using a stock cage/pulley), then YES you will need a new chain.  If you are installing an Adventure System, it's a case by case situation as sometimes you WILL but yet sometimes you will NOT need a new chain.


Q: Is your customized Custom Shop systems still available?

A: Absolutely!  Please see the link below: 



Q: What is the recommended maintenance for an SLF Motion System?

A: Because we choose to use only coated hybrid ceramic bearing in all our pulley wheels, maintenance is kept pretty simple.  We simply recommend every 750-1000 miles to check tension on all major bolts and connection points to the rear derailleur.  At this time, it is also a good idea to remove the chain and spin each pulley wheel to ensure best performance.  See next FAQ if your bearing needs maintenance...


Q: My pulley wheels don't spin like they did when new?

A: Watch the following video for a step-by-step  "How To" tutorial on cleaning your SLF Motion hybrid ceramic bearings.


Q: Do I need to lube, oil, or grease my pulley wheel bearings?

A: This is environment dependent.  For absolute highest performance ON-ROAD applications, we recommend running your pulley wheels "dry"...and we are able to do this thanks to our coated steel races.  Some customers have mentioned that "dry" pulley wheels are too "loud" - if this is the case, 1 drop of lightweight oil will eliminate any noise.  For OFF-ROAD (and gravel) applications, we recommend running your pulley wheels with grease.  We ship all EVO 1X Systems pre-greased from our HQ.
